Parpi - MORE | Innovation in Steelmaking

Parpi - MORE | Innovation in Steelmaking: The PARPI system consists of two water cooled lances; one is used to inject oxygen at supersonic velocity and one injects carbon fines. The lances are supported and moved by a manipulator installed on the rigid platform at a certain distance from slag door on the right or left side.On request, the carbon tip could incorporate the innovative MSF-Mixed Swirl Flame burner mode to melt the scrap that remains trapped within the furnaces slag tunnel.The lances are supported and manipulated by a rotating turret installed on the rigid platform and they are held in place by a rear quick connection support which allows a fast removal and replacement.BENEFITSRemote operation from furnace control room in a safe positionIncreased oxygen efficiency and carbon fines recoveryEasy and fast lance removal by a quick connection systemThe flow of oxygen obtainable with this system allows for high decarburization speedThe carbon injection into the slag promotes FeO and MnO reduction with consequent early slag foaming and better control of the metallic yield.

Parpi Oxygen and carbon water cooled lances that operates through the furnace slag door

The PARPI system consists of two water cooled lances; one is used to inject oxygen at supersonic velocity and one injects carbon fines. The lances are supported and moved by a manipulator installed on the rigid platform at a certain distance from slag door on the right or left side.

On request, the carbon tip could incorporate the innovative MSF-Mixed Swirl Flame burner mode to melt the scrap that remains trapped within the furnaces slag tunnel.

The lances are supported and manipulated by a rotating turret installed on the rigid platform and they are held in place by a rear quick connection support which allows a fast removal and replacement.

BENEFITS

  • Remote operation from furnace control room in a safe position
  • Increased oxygen efficiency and carbon fines recovery
  • Easy and fast lance removal by a quick connection system
  • The flow of oxygen obtainable with this system allows for high decarburization speed
  • The carbon injection into the slag promotes FeO and MnO reduction with consequent early slag foaming and better control of the metallic yield
